Abstract:

The Next Generation Network (NGN) is a telecommunications system that converges all services and information into packets for transfer, accommodating technical advancements high-speed and diversified services through its multilayer architecture. The NGN enables users to consistently and efficiently obtain services, and 5G cellular communication is a viable technology to meet the demand for high data rates in the future, particularly with its mmwave capacity. However, one of the major problems that the new generation faces is non-line-of-sight status, which results from higher frequencies' extreme vulnerability to interference from obstructions and misalignment. This special property makes it more difficult for the widely used Transmission Control Protocol (TCP) to achieve good throughput and low latency across an equitable network. TCP must modify the congestion window size in accordance with the state of the network, but it is unable to effectively adapt to its congestion window, resulting in degradation of the protocol's throughput. This research presents an in-depth analysis of trustworthy communications in 5G networks, examining how TCP affects 5G mmWave networks, the mechanisms and parameters of TCP that portrays the behavior of 5G networks, and a study of the existing problems, and ideas to be fixed. It also suggests a viable study of different methods to enhance reliable communications in 5G networks.

Abstract:

The telecommunication numbering system in Indonesia currently complies to the International TelecommunicationUnion (ITU) standard, that is ITU-T E.164. In accordance to both technology development and the growing of network users, ITU has also been designing future infrastructure network concept, namely Next Generation Network Infrastructure (NGNI). In its technical paper, ITU discusses future generation’s specification as well as current network migration scenarios towards Next Gereration Network (NGN) in developing countries and its impact on regulations, business processes, and the numbering system. The scenario described in the concept is yet universal and the implementation would be highly depending on the conditions of ones country. This paper proposes the roadmap of numbering system from the current state into NGN numbering for the case of Indonesia. The method used in this paper are benchmarking with several countries that have started with the transformation process, forecasting with regression method based on the existing trends and descriptive analysis. This paper has proposed the stages of numbering roadmap towards NGN numbering system, the achievement parameters, and the indicators that are suitable for Indonesia.

Abstract:

Modern subscribers of infocommunication services require a wide class of different services and applications, implying a wide variety of protocols, technologies and transmission rates. Networks are overloaded in the prevailing situation in the market of infocommunication services: they are overflowing with numerous customer interfaces, network layers and are controlled by too many control systems. High operating costs are pushing operators to look for solutions that simplify the operation, while maintaining the possibility of creating new services and ensuring the stability of existing sources of income from the provision of communication services. The NGN concept is the concept of building next-generation communication networks (Next-generation network), providing an unlimited set of services with flexible settings for their management, personalization, creation of new services through the unification of network solutions. Multiservice network is a communication network that is built in accordance with the NGN concept and provides an unlimited set of infocommunication services (VoIP, Internet, VPN, IPTV, VoD, etc.). An NGN is a packet-switched network suitable for the provision of telecommunication services and for the use of multiple broadband transport technologies with QoS enabled, in which the service-related functions are independent of the applied transport technologies. The main feature of NGN networks is the differentiation between services and transport technologies. This allows to view the network as a logically divided entity. Each layer of the network can evolve independently without affecting other layers. Inter-layer communication is based on open interfaces. The logical separation principle allows the provision of both existing and innovative services access technologies regardless of the used transport. The basic principle of the NGN concept is to separate from each other transfer and switch functions, call control functions and service control functions.

Abstract:

With the development of networks and wideband technology, Next Generation Network (NGN) evolves into integrated transmission network of the multimedia information which including data, voice, image, the real-time tasks, etc. The traditional IP network provides only "best-effort" service and cannot meet the needs of multi-media applications and the different demands of a variety of users for network transmission quality. On the basis of a detailed analysis to Differentiated service (DiffServ) model and the characteristics of MPEG-4 encoding, the QoS control strategy of video streaming in NGN is proposed. That is a QoS control strategy which uses priority of Inter-Frame combining with DiffServ model in network congestion. Simulation and testing results show that the strategy can improve the transmission quality of the video stream effectively in the case of limited bandwidth.

Abstract:

Next Generation Networks (NGN) is the evolution of the telecommunication core. The user has to execute multi-pass Authentication and Key Agreement (AKA) procedures in order to get access to the IP Multimedia Subsystem (IMS). This causes overhead on the AAA server and increases the delay of authenticating the user and that is because of unnecessary and repeated procedures and protocols. This paper presents an enhanced one-pass AKA procedure that eliminates the repeated steps without affecting the security level, in addition it reduces the Denial of Service (DoS) attacks. The presented mechanism has minimal impact on the network infrastructure and functionality and does not require any changes to the existing authentication protocols.

Abstract:

The Next Generation Network (NGN) architecture was proposed for delivering various multimedia services with guaranteed quality. For this reason, the elements of the IP Multimedia Subsystem (IMS) concept (an important part of 4G/5G/6G mobile networks) are used in its service stratum. This paper presents comprehensive research on how the parameters of an IMS/NGN network and traffic sources influence mean Call Set-up Delay (E(CSD)) and mean Call Disengagement Delay (E(CDD)), a subset of standardized call processing performance (CPP) parameters, which are significant for both network users and operators. The investigations were performed using our analytical traffic model of a multidomain IMS/NGN network with Multiprotocol Label Switching (MPLS) technology applied in its transport stratum, which provides transport resources for the services requested by users. The performed experiments allow grouping network and traffic source parameters into three categories based on the strength of their effect on E(CSD) and E(CDD). These categories reflect the significance of particular parameters for the network operator and designer (most important, less important and insignificant).

Abstract:

The subject of the study is multiservice communication network using the concept NGN (Next Generation Network) based on the open network architecture IMS (Internet Protocol Multimedia Subsystem), supporting a wide range services. The basis of this architecture is the IMS core, consisting of a set of specialized modules responsible for various functions for customer service. The purpose of the article is to analyze the existing technical capabilities of the IMS multimedia messaging subsystem and perspective solutions for the functioning of the NGN/IMS network efficiency in providing multimedia service. As the efficiency of the system, the capacity NGN/IMS networks is selected using the signaling system and protocols NGN. The capacity NGN/IMS networks during the establishment of a multimedia session was analyzed and the functional architecture of the IMS multimedia messaging subsystem that determine the interaction NGN signaling systems an protocols was explored. Manage the presentation Triple Play services to subscribers and simultaneously modify the media stream within the session allows the protocol for the initialization of the SIP and Diameter sessions, which are the main IMS signaling protocol. One of the important requirements for the IMS subsystem is the maintenance QoS (Quality of Service). A mathematical model for estimating the quality of communication services using a system GI/G/1/N based on the theory diffusion approximation is proposed. The research presented in this paper is very important for the theory queuing systems, since the article proposes a method for investigating multiservice communication networks with non-Poisson incoming flow and effective results are obtained for NGN/IMS networks. On the basis of the model analytical expressions are obtained, which allow evaluating the performance indicators of the Triple Play service. The proposed mathematical model can be used to solve a wide range of practical problems, including the management multiservice traffic in the process its transmission in multiservice telecommunications networks, taking into account the quality of service classes. Thus, studies NGN/IMS network capacity indicators using SIP protocols are relevant.

Abstract:

Over a long period of development of the network communication general user (NCGU), various models have been developed, focused on the service of voice traffic. In the next generation NGN heterogeneous communication network, voice traffic service has become one of the applications. This application was subject to stringent timing requirements (latency and loss). Further development took place to develop new applications that impose even more severe service requirements. Such applications have had a significant impact on the requirements and timing of next generation communications networks. In this regard, it was proposed in various recommendations to distinguish networks that provide services with strict requirements for time parameters into a new class of networks and call them networks with low and ultra-low delays.

Abstract:

Next Generation Network (NGN) faces the challenge of the rapidly increasing amount of signaling. The growing amount of signaling is a consequence of several reasons arising from the fact that signaling is the main source of network intelligence, analysis, and user behavior monitoring. With the increase in signaling load and complexity, the network management becomes a challenging issue that can impact overall Quality of Service (QoS). To confront this issue, there is a need for reliable and forehand signaling transmission in NGN. As there is much confusion about the interpretation of this concept, this paper aims to provide an overview of the evolution of signaling transmission. Migration towards NGN is analyzed from the signaling perspective. The NGN signaling protocols and related transmission requirements are identified. Through the discussion of standard approaches, the paper considers our previously published approach to signaling transmission along with the current issues and emerging opportunities.

Abstract:

The rapid evolution of the telecommunication domain increases the performance of different access networks continuously. New services, especially in the domain multimedia content distribution, require higher and higher bandwidth at the user’s and service provider’s side. Multimedia services like Video on Demand, IPTV, and live streaming were introduced in the past and are still improved in quality and quantity. Multimedia streams and Peer to Peer (P2P) file sharing dominates the worldwide Internet traffic nowadays and will continue further (Schulze, 2009). The user acceptance of enjoying multimedia content over the Internet will grow steadily together with the increasing quality of the available multimedia content. Network operators and service providers have to face the growths by increasing their service platform with higher performance and bandwidth or introducing a scalable solution. In this paper, the authors present an algorithm for scalable P2P live streaming in Next-Generation-Networks (NGN) that addresses this challenge. An evaluation proves the performance of the implementation of this algorithm in a demo scenario.

Abstract:

Currently it is assumed that requirements of the information society for delivering multimedia services will be satisfied by the Next Generation Network (NGN) architecture, which includes elements of the IP Multimedia Subsystem (IMS) solution. In order to guarantee Quality of Service (QoS), NGN has to be appropriately designed and dimensioned. Therefore, proper traffic models should be proposed and applied. This requires determination of queuing models adequate to message inter-arrival and interdeparture time distributions in the network. In the paper the above mentioned distributions in different points of a single domain of NGN are investigated, using a simulation model developed according to the latest standards and research. Relations between network parameters and obtained message inter-arrival as well as interdeparture time distributions are indicated. Moreover, possibility of approximating the above mentioned distributions using phase-type distributions is investigated, which can be helpful in identifying proper queuing models and constructing an analytical model suitable for NGN.

Abstract:

The next generation wireless network needs to provide seamless roaming among various access technologies in a heterogeneous environment. In allowing users to access any system at anytime and anywhere, the performance of mobility-enabled protocols is important. While Mobile IPv6 is generally used to support macro-mobility, integrating Mobile IPv6 with Session Initiation Protocol (SIP) to support IP traffic will lead to improved mobility performance. Advanced resource management techniques will ensure Quality of Service (QoS) during real-time mobility within the Next Generation Network (NGN) platform. The techniques may use a QoS Manager to allow end-to-end coordination and adaptation of Quality of Service. The function of the QoS Manager also includes dynamic allocation of resources during handover. Heterogeneous networks raise many challenges in security. A security entity can be configured within the QoS Manager to allow authentication and to maintain trust relationships in order to minimize threats during system handover. The next generation network needs to meet the above requirements of mobility, QoS, and security.

Abstract:

The IP age of networks and services is increasing very quickly. Starting from its VoIP, NGN, and IMS to today's IP services landscape, which includes fixed and mobile high-definition (HD) voice, HD video calling, unified communications (UC), video conferencing, and telepresence, cooperation, instant messaging (IM), and the rich communication suite (RCS). Convergence is one of the most significant current trends in the ICT sector. It has changed the way services are delivered and obscured the distinction between fixed and mobile services. The transition to Next-Generation Networks (NGN) is the most important next phase in the ICT sector's convergence-driven evolution. In the realms of NGN, VoIP, and IMS, there is no PSTN equivalent; instead, there are "IP islands " that locate the total value of an IP service. The next basic step is to expand the arrive of those services across a totally interconnected cross-network premise in order to maximize their overall esteem among their target audiences. The liberalization of infrastructure services depends on managing the interconnection interface between the competitive and regulated sectors. These paper outlines regulation issues raised by IP-based interconnection and examine the current practices and procedural ways that being developed to address these concerns.

Abstract:

Abstract Growing expectations for a fast access to information create strong demands for a universal telecommunication network architecture, which provides various services with strictly determined quality. Currently it is assumed that these requirements will be satisfied by Next Generation Network (NGN), which consists of two stratums and includes IP Multimedia Subsystem (IMS) elements. To guarantee Quality of Service (QoS) all NGN stratums have to be correctly designed and dimensioned. For this reason appropriate traffic models must be developed and applied, which should be efficient and simple enough for practical applications. In the paper such a traffic model of a single domain of NGN with transport stratum based on Multiprotocol Label Switching (MPLS) technology is presented. The model allows evaluation of mean transport stratum response time and can be useful for calculating time of processing requests in the entire NGN architecture. Results obtained using the presented model are described and discussed. As a result of the discussion, elementary relationships between network parameters and transport stratum response time are indicated.

Abstract:

This paper shortly describes the IP QoS System which offers strict quality of service (QoS) guarantees in IP-based networks and supports a number of, so called, classes of services. Such solution requires to implement in the network a set of QoS mechanisms and algorithm working on packet, connection request and provisioning levels. Furthermore, we require signaling system for informing the network about new connection request and network resource allocation capabilities for providing required resources to given connection. The IP QoS System is based on the next generation networks (NGN) and differentiated services (DiffServ) architectures and, at least for now, it is designed for single domain only.

Abstract:

The first experience of quality by multimedia applications’ users takes place during the setup phase of a new connection. If the setup phase is not accepted or “slowly accepted”, the confidence of the user decreases. The user becomes more sensitive when he/she pays the connections with assured quality of service (QoS). In this case, the process of call request should be also accomplished with QoS guarantees. This paper presents the signaling sub-system implemented within the EuQoS system. The EuQoS signaling process follows main assumptions of next generation networks (NGN) architecture and performs tasks related with codec agreement between multimedia end users, admission control and resource reservation functions. In this paper, we present analytical, simulation and experimental results showing the impact of signaling system performance on quality of experience (QoE) for the potential users of multi-layer EuQoS system. In particular, the presented approach aims at ensuring user QoE of the connection setup phase by ensuring QoS for transferring signaling messages by the network.

Abstract:

E-Health services comprise a broad range of healthcare services delivered by using information and communication technology. In order to support existing as well as emerging e-Health services over converged next generation network (NGN) architectures, there is a need for network QoS control mechanisms that meet the often stringent requirements of such services. In this paper, we evaluate the QoS support for e-Health services in the context of the Evolved Packet System (EPS), specified by the Third Generation Partnership Project (3GPP) as a multi-access all-IP NGN. We classify heterogeneous e-Health services based on context and network QoS requirements and propose a mapping to existing 3GPP QoS Class Identifiers (QCIs) that serve as a basis for the class-based QoS concept of the EPS. The proposed mapping aims to provide network operators with guidelines for meeting heterogeneous e-Health service requirements. As an example, we present the QoS requirements for a prototype e-Health service supporting tele-consultation between a patient and a doctor and illustrate the use of the proposed mapping to QCIs in standardized QoS control procedures.

La provisión de Calidad de Servicio (QoS, Quality of Service) es uno de los aspectos más importantes en el desarrollo de la Red de Nueva Generación (NGN, Next Generation Network). En este sentido, el suministro de QoS en redes basadas en IP, requiere de un proceso de negociación en el que se deben identificar los protocolos e interfaces necesarias para establecer de forma clara los procedimientos a ejecutar entre los elementos y funciones involucrados. Este artículo describe el proceso de negociación de calidad del servicio en el contexto de la NGN, donde el usuario, la capa de transporte y la capa de servicio acuerdan los parámetros de QoS de la sesión que se va a establecer para lograr un servicio con calidad.

Abstract:

The IP QoS System is based on next generation networks (NGN) and differentiated services (DiffServ) architectures. Its main part is a signaling system, which allows to send a request from a user to the system for establishing new connection with predefined quality of service assurance. In this paper we present trial results of the proposed signalling system. The experiments were performed to measure setup delay utilizing artificial call generator/analyzer. To obtain results we assumed different distributions of interarrival and call holding times based on the literature. The results show that the setup delay strongly depends on access time to network devices, however also on the assumed call holding time models.

Abstract:

The performance indicators corporate multi-service networks based on the architectural concept of the following Next Generation Network (NGN) and Future Networks (FN) using a number of innovative technologies are considered. A significant difference between such networks and previous generation networks is that the architecture of future networks is based on technologies software defined networks, virtualization network functions and the multimedia communications subsystem. As a criterion for complex performance indicators corporate multiservice networks, we selected throughput, the coefficient effective use hardware and software systems, various resources, and probability-time characteristics. As a result of the study, a method for calculating the complex throughput indicators corporate multiservice networks based on the architectural concept NGN and FN using SDN (Software Defined Networking), NFV (Network Functions Virtualization) and IMS (Internet Protocol Multimedia Subsystem) technologies is proposed. Th essence of the new method is to find relationships with which you can calculate the maximum throughput of the communication network and the areas feasible solutions of the basic equation that belong to it. System and technical analysis showed that the transmitted heterogeneous traffic has a special structure – self-similarity properties (scale invariance) and a quantitative assessment of the degree traffic self-similarity using the Hurst parameter. Based on the proposed calculation method, the complex indicators of corporate multiservice networks are examined taking into account the parameters traffic self-similarity, QoS (Quality of Service) and QoE (Quality of Experience). Resource management methods in network nodes were studied to improve the throughput characteristics taking into account the numerous QoS & QoE parameters and the coefficient effective use hardware and software systems was determined. Based on the calculation method, analytical expressions have been obtained to evaluate the complex indicators corporate multiservice networks in establishing connections and in providing multimedia services with the necessary parameters. A numerical analysis is carried out and a graphical dependence of the maximum network throughput on the total number software and hardware systems is constructed for a given system load factor.

Abstract:

With an ever increasing penetration of Internet Protocol (IP) technologies, the wireless industry is evolving the mobile core network towards all-IP network. The IP Multimedia Subsystem (IMS) is a standardised Next Generation Network (NGN) architectural framework defined by the 3rd Generation Partnership Project (3GPP) to bridge the gap between circuit-switched and packet-switched networks and consolidate both sides into on single all-IP network for all services. In this paper, we provide an insight into the limitation of the presence service, one of the fundamental building blocks of the IMS. Our prototype-based study is unique of its kind and helps identifying the factors which limit the scalability of the current version of the presence service (3GPP TS 23.141 version 7.2.0 Release 7 [1]), which will in turn dramatically limit the performance of advanced IMS services. We argue that the client-server paradigm behind the current IMS architecture does not suite the requirements of the IMS system, which defies the very purpose of its introduction. We finally elaborate on possible avenues for addressing this problem.

Abstract:

Develop a proposal for a management model that allows, through knowledge management, to preserve the quality of services during the technological evolution of networks in a telecommunications company. Today, BaghTel is considered the main telecommunications company in Iraq and some time ago it was acquired by the Iraqi government, which has generated a significant organizational transformation, added to the fact of the rapid technological evolution and the strong competition of the sector. These factors give rise to concern on the part of certain units regarding which management model can best adapt to these changes. In addition to these reasons, there is a need for companies like BaghTel to improve the management of this type of updates or migrations, which would later translate into improvements in the quality of services provided by the company. This study seeks to propose a management model that allows optimizing the administration of networks and services, during the organizational transformation processes that occur in a telecommunications company as a result of today's technological evolution. The importance of this work lies in the opportunity to optimize, through a management model, the way to control an important technological change, which will ensure and improve the service levels that any telecommunications company provides to its end users. The final process, measures and assessments, include a viewing and use of management indicators of the results obtained in BaghTel's Specialist Networks Management; this consists essentially of a periodic monitoring and evaluation of the key variables in the management of the TDM (Time Division Multiplexing) and NGN (next generation of networks) networks;

Abstract:

The article is devoted to the problems of advanced workforce management systems WFM (Workforce Management) of post-NGN telecommunication operators, a formalized approach to the description of extended WFM functionality and mathematical WFM models are discussed. The proposed approach allows to develop new WFM tools for telecommunications operators to increase their performance, to manage more effectively the work schedules of engineering employees of the company, visit customer sites, and control the workload of engineers in real-time. Workforce Management systems (WFM) of Next Generation Networks (NGN) are becoming more and more important. Compared to the routine distribution of requests between telephone technicians in the repair bureau of the old Public Switched Telephone Network (PSTN) in the last century, the modern WFM system operates with a disproportionately large set of functions, a wide range of professional competencies and key performance indicators (KPIs). In partnership with WFM, other new information technology tools (IT-landscape) of the telecommunications operator, elements of BSS (Business Support Systems), human resource accounting (HR) software, enterprise resource planning (ERP) systems, other workforce planning, and management tools employee vacations, the timing of basic engineering operations at the operator's and customer's premises, and other support tools to optimize the performance of the required work by personnel, increase productivity and reduce costs.

The IMS communication platform is the most suitable fabric for integrating IoT and Cloud. This paper focuses on different aspects including Cloud Service Framework, Data Sensing and Communication Technology, Collaborative Authentication and Privacy Protection Mechanism, Operation, Administration, and Maintenance (OA&M), Mobility and Energy-Saving Management, and Application Services. This paper not only provides the discussion of open challenges, but also proposes a possible solution based on the above-mentioned aspects for Future Internet.

C&C08 is responsible for the bottom access and transfer of the fixed-phone calls. Applying the computer telephony integration (CTI) technology we can realize the telephone call management through a computer. Using this system, fixed telephone managers can conduct limitation control for cluster management users information and implement list query of cost easily, so that managers can know the detail cost. In addition, based on the present situation of the telecom business, we designed four telecommunication services for enterprises and institutions, and added them to the fixed-phone cluster management system. For the cluster management users, they can subscribe to those services according to their needs.

Abstract:

Next Generation Networks (NGNs) are expected to handle heterogeneous technologies, services, verticals and devices of increasing complexity. It is essential to fathom an innovative approach to automatically and efficiently manage NGNs to deliver an adequate end-to-end Quality of Experience (QoE) while reducing operational expenses. An Autonomous Network (AN) using a closed loop can self-monitor, self-evaluate and self-heal, making it a potential solution for managing the NGN dynamically. This study describes the major results of building a closed-loop Proof of Concept (PoC) for various AN use cases organized by the International Telecommunication Union Focus Group on Autonomous Networks (ITU FG-AN). The scope of this PoC includes the representation of closed-loop use cases in a graph format, the development of evolution/exploration mechanisms to create new closed loops based on the graph representations, and the implementation of a reference orchestrator to demonstrate the parsing and validation of the closed loops. The main conclusions and future directions are summarized here, including observations and limitations of the PoC.

Perkembangan teknologi telekomunikasi yang semakin pesat, membuat para operator dan vendor telekomunikasi harus dapat menyediakan layanan telekomunikasi yang aman, cepat, dan multi guna, untuk mendorong terciptanya ekosistem layanan telekomunikasi yang beragam bagi para penggunanya. Next Generation Network (NGN) merupakan sebuah teknologi masa depan yang mendukung beberapa layanan terintegrasi seperti voice, data, dan multimedia. Hal utama dari konsep NGN adalah konvergensi dan layanan yang berbasis IP sehingga diperlukan sebuah teknologi yang dikenal dengan IP Multimedia Subsystem (IMS). Agar pengiriman data dalam layanan IMS menjadi lebih efektif dan efisien maka diperlukan sebuah teori antrian yang tepat untuk digunakan sebagai pengatur aliran paket data. Penelitian ini melakukan pengamatan terhadap beberapa layanan pada jaringan IMS dengan menggunakan tiga teori antrian yang berbeda yaitu First In First Out (FIFO), Priority Queuing (PQ), dan Weighted-Fair Queuing (WFQ). Pengamatan dilakukan terhadap layanan Video Conference dan VoIP. Dari hasil simulasi dapat diketahui bahwa teori antrian WFQ pada layanan video conference menghasilkan rata-rata delay sebesar 9.22 ms , delay variation sebesar 0.036 ms dan packet loss sebesar 0.88%. Sedangkan untuk layanan VoIP menghasilkan rata-rata delay sebesar 144 ms, delay variation sebesar 0.021 ms, dan packet loss sebesar 0.05% serta menghasilkan rata-rata throughput sebesar 7.052 Mbps, sehingga teori antrian yang tepat digunakan dalam jaringan IMS dalam penelitian ini adalah WFQ.

Abstract:

З появою мультисервісних мереж з’явилися інтелектуальні сервіси (INS) і, відповідно, новий тип трафіку. Протягом довгого часу вважалося, що мережний трафік відповідає пуасонівським процесам, але подальші дослідження довели, що в трафіку деяких мереж наявний ефект самоподібності. Через властивості самоподібного трафіку традиційні методи розрахунку характеристик функціонування мереж дають занадто оптимістичні результати і призводять до недооцінки реального навантаження. Виникає актуальне питання визначення наявності ефекту самоподібності трафіку, що містить заявки на INS, а також урахування цього ефекту при формуванні аналітичної моделі інтелектуальної надбудови NGN (Next Generation Network). Саме цим питанням присвячена дана робота. На основі аналізу існуючих методів розрахунку показника Херста, що надає можливість визначити характер трафіку, обрано R/S метод, оскільки його використання дозволяє аналізувати велику кількість даних, а також не містить занадто великого обсягу обчислень. Даний метод реалізований за допомогою програми AutoSignal. Виходячи з аналізу отриманих результатів можна стверджувати, що трафік, що містить заявки на INS – це самоподібний процес. Ефект самоподібності проявляється в широкому діапазоні часу – від декількох годин до року. Проведені дослідження характеру трафіку визначили можливість вирішення актуальної задачі – розробки аналітичної моделі інтелектуальної надбудови NGN, яка відповідає за управління наданням INS, з урахуванням самоподібності трафіку. Для побудови аналітичної моделі інтелектуальної надбудови було використано апарат теорії масового обслуговування. Запропонована аналітична модель інтелектуальної надбудови, яка ураховує самоподібність потоку заявок на INS, надає можливість визначити потрібні мережні ресурси для забезпечення необхідного значення ефективності управління наданням INS.

Abstract:

Long Term Evolution (LTE) is a leading 4G wireless broadband technology developed by the Third Generation Partnership Project (3GPP) Release 8. LTE is expected to provide very fast, highly responsive and cost effective data services and appears itself to be the right technology at the right time. LTE is becoming an ultimate choice for 4G services around the world due to its higher data rates and lower latency objectives. E-Health services comprise a wide range of healthcare services delivered by utilizing information and communication technology. In order to help existing and emerging e-Health services over converged next generation network (NGN) architectures, there is a need for network QoS control mechanisms that meet the often stringent requirements of such services. The mobile Health (m-health) is currently uniting major academic research worldwide to achieve innovative arrangements in the areas of healthcare. However, there are several challenges and issues that need to be addressed. In this paper we have proposed m-health care system based on 4G LTE network communication instead of existing 3G communication system. We will be monitoring QoS parameters like Delay, Throughput, Jitter, Energy Efficiency and Packet Data Rate for comparing 3G and 4G LTE usage over health care applications. We will further experiment the parameters with graph based analysis.
